inconvenient breasts
When breasts get in the way by getting stuck, ruining clothes, knocking things over, impeding line of sight, or even accidentally whacking someone on the head. Apparently there can be too much of a good thing.
This is usually when breasts are too large, but it can also apply to breasts that are too small if that is a detriment in some way. Please do not confuse with breast envy.
